Been awhile but still only one posting on this one.Ha ha Still have my 37 and see I do not proof read still. 1938 is last small cab.First with gas fill neck in right side of cab.1937 you had to lift a seat to put gas in the inside tank.

Three years have a cab that looks like this with the bowties on the hood sides.Gone on this one.Late 36,37,and 38.38 is the only one with a gas filler neck in the cab.On the left side..38 last year with push knobs instead of handles to open doors inside.Cabs become bigger in 39 and windshield is split but still crank out through early 47.

This is a 37.I have a 37 Chevy pu and had a 38.Same cab and fenders.38 is the last real small cab.Metal looks really good.They usually rust at the bottom of the fender and doors.From my motorcycle trips looks MT,SD,WY,parts of the west.
